SOLIDIFIED DEODORANT AND INSECTIGIDE.

Application file-d March 2, 1925. Serial No. 12,661.

insecticidal material in the form of blocks.

The chief object of the invention is to produce a block of materialsuitable for a deodorant or an insecticide or both which will have thenecessary evaporation orvaporization rate and which will have thenecessary physical form to secure or assure said rate, and which willfurthermore have such physical form that it may be readily handled andalso readily handled without danger of breakage andwhich when in usewill not disintegrate as it, approaches exhaustion.

The chief feature of the invention consists in forming the suitablematerial into suitable block form. The resultant block has aperturesextending therethrough for presenting an apparently larger mass of material from a predetermined amount thereof so that said material may bemore readily handled aswell as the gripping port1ons provided by theapertures or recesses formed.

therein. The enlargement of the over all superficial area of the blockprovides an 1ncreased surface area for securing a greater amount ofvapor from the same mass of material than otherwise would be obtainablefrom a regular and solid mass of the same material.

A further feature of the invention consists in the addition of areinforcement incorporated the block, whereby strength is imparted tothe block so that in shipment the block, if brittle, will not crack orbreak, and

furthermore so that the block when in use,

will not disintegrate or crumble as it approaches complete exhaustion,but will maintain its block form substantiallyto the end of the life ofthe block. r

The full nature of the invention will be understood'from theaccompanying drawings and the following descrlption and claim:

In the drawings Fig. 1 is a central sectional view of a mold, thereinforcement and the material in the mold for forming the block. Fig. 2is a perspective view of the completed block. Fig. 3 is a similar viewof the completed block with one-fourth removed showing the removedsurfaces in section.

In the drawings 10 indicates a mold which herein is shown rectangular inoutline with upwardly and outwardly inclined walls 11. At suitabledistances, extending upwardly fro the base, are frusto conical members12. These constitute cores for the mold and they ay be of suitable formbut herein are shown rusto conical. Ireferably they are tapered in thedirection of the top of the mold.

The material to form the deodorant and insecticide, either or both, ispoured into the mold after the reinforcing member or members is or areapplied to the mold. Herein the reinforcing member is indicated by thenumeral 13 and the same is provided with apertures 14 that register withthe cores:

The'reinforcement is herein shown as consisting of a single plate or.sheet of screen wire having the apertures 14 of such size that theplate or screen is positioned approx- 'mold does. not expose any face ofthe rein- The' reinforcement is of such 1 for-cement. character that itprevents breakage of the block in shipment and also prevents crumblingof the blockwhen the same approaches exhaustion.

The block may be removed from the mold by chilling the same andsubsequently heating the mold or by any other convenient means. Theresultant block produced by the foregoing process is shown in Figs. 2and 3. It will be noted that the total surface exposed to the atmosphereis increased over the over all dimensions by reason of the surfaces ofthe conical openings 16 formed in the resultant block 17 which includesthe reinforcement 13.

A suitable material satisfactory not only as an insecticide but as adeodorant, or both, is paradichlorbenzol. This material is commerciallyavailable in the form of crystals and is generally marketed in thatform. These crystals are also colorless and have a melting po'intfofabout 56 degrees. This material also has the property that upon heatingor application of pressure the crystals fuse and a liquid results. Thisliquid can be readily poured into molds and thus blocks produced. Thismaterial, furthermore, has a pleasing odor and when exposed to the atmoshere will volatilize without leaving a resi ue. Thus there is availablea solid material at normal temperature which will volatilize undernormal room temperatures. If desired there may be added to the materialhereinbefore mentioned, a suitable perfume or odoriferous substancewhich in turn will partially mask the odor of the paradichlorbenzol.Furthermore, there may be included in the material more potent agenciesfor the purpose desired.

The invention claimed is:

A disinfecting block formed of materials susceptible to vaporizing andcrumbling, a reinforcing element in said block, comprising a wovenfabric embedded wholly within said block and terminating at its ends andedges a slight distance inwardly from the corresponding ends and edgesof said block.

In witness whereof, we have hereunto affixed our signatures.
